Non-linear matter power spectrum covariance matrix errors and cosmological parameter uncertainties
The covariance of the matter power spectrum is a key element of the analysis of galaxy clustering data. Independent realizations of observational measurements can be used to sample the covariance, nevertheless statistical sampling errors will propagate into the cosmological parameter inference poten...
